public final class
CollectiveReduceV2
Mutually reduces multiple tensors of identical type and shape.
`is_stateless` means each op does not need control dependencies to other collective ops. In this case, keys that are unique at runtime (e.g. `instance_key`) should be used to distinguish collective groups.

Inherited Methods
Public Methods
public Output<T> asOutput ()
Returns the symbolic handle of a tensor.
Inputs to TensorFlow operations are outputs of another TensorFlow operation. This method is used to obtain a symbolic handle that represents the computation of the input.
public static CollectiveReduceV2<T> create (Scope scope, Operand<T> input, Operand<Integer> groupSize, Operand<Integer> groupKey, Operand<Integer> instanceKey, Iterable<Operand<?>> orderingToken, String mergeOp, String finalOp, Options... options)
Factory method to create a class wrapping a new CollectiveReduceV2 operation.
Parameters
| scope | current scope |
|---|---|
| options | carries optional attributes values |
Returns
- a new instance of CollectiveReduceV2
